Perhaps you need to broaden your camping experience?
Try some of the lesser known, less popular parks. It really depends on why you are going to the places that you are going. If you are hung up on state parks because you think they are cheaper, try the city/county parks. As for private parks, I find that Passport America gets the price to the same or below state parks (which are pricing themselves out of my range for a partial hookup site). I tend to use parks as a place to park my rolling motel room and visit the local area. I don't stay in "destination" parks. There are more things to see than what's inside a "destination" park.
I will give you a tip, there are plenty of parks that are nice but get a bad rating because some people are intimidated by the "permanent" RVers. Or "older RVs". Is that you? People tend to stay long term for two reasons.... price and people. I am a "permanent" in an "older RV". I promise that you and your shiny new RV won't get cooties from me or my older RV. As a matter of fact, I would probably never say anything to you. It's the dreaded "overnighters" that trash and tear our park. And that goes for every park that I have long termed in.
I lived, long term, in one park that consistently got bad reviews for having long term "permanent" rvers who were pushed out of the way, against a wall. That left all the pull-thru sites open. But the pull thru sites were w/e and they used the dump station. The horrible terrible "permanents" who were all in the shortish back in sites had sewer hookups. Some of the reviews got really nasty because the full hook up were used by the long term. Yet, even when there were FHU sites open, they didn't stay over night in them. I think it had to do with being next to a long term "permanent." Did they think they were going to be robbed? Oddly, the only people who stole from us was the overnighters.
